Abstract:
A decoder may receive, for a block, an indication of decoder-side-prediction and a reconstructed residual block from a bit stream. The decoder may generate, for each respective intra prediction mode of a plurality of intra prediction modes, a reconstructed block based on: a prediction block generated for the respective intra prediction mode; and the reconstructed residual block. The decoder may determine a selected prediction mode, from the plurality of intra prediction modes, for the block based on a visual quality of each of the reconstructed blocks. The decoder may decode the block based on the indication of the decoder-side-prediction and the selected prediction mode.
